CARD-CATALOGUE.

SPECIFICATION forming part of Letters Patent No. 528,692, dated November6, 1894.

Application filed November 6,1893. Serial No. 490,158. (No model.)

To all whom it may concern:

Be it known that I, ALEXANDER J. RU- poLrH, a citizen of the UnitedStates, residing 1n the city and county of San Francisco, State ofCalifornia, have invented an Improvement in Card-Catalogues; and Ihereby declare the following to be a full, clear, and exact descriptionof the same.

My invention relates to improvements in what are termed card catalogues.

It consists in certain details of construction which will be more fullyexplained by reference to the accompanying drawings, in which- Figure lis a view showing one face of a card. Fig. 2 is a View of the reverseside of the card showing the impression with printed matter pasted inone corner. Fig. 3, shows a blank from which the card is formed.

In the use of card catalogues, a standard size of cards are used made ofbristol or heavy cardboard, ruled upon one side, and having a holepunched near the center of the lower edge. A series of cards is placedon their edges in the drawer, the side with the hole lying next thebottom of the drawer. A metal rod is passed through the front wall ofthe drawer and passes through all the corresponding holes in the cards,thus keeping the cards fastenedin place, but movable for examination,the rod preventing any misplacement or. removing of the cards from thedrawer. On these cards are printed or written the subject matter, theauthors, or title entry or cross reference, each of these entries on a,single independent card, and all these cards are alphabeticallyarranged. Many of these entries could be secured from other sourcesalready printed as in library bulletins and catalogues or in periodicalsdevoted to literature which publish regularly lists of titles of newpublications. By utilizing this printed material, a great saving of timeand legibility are secured, not to speak of greater accuracy '1nspelling.

I do by forming an intaglio space on one side of the card of such depthas to correspond with the thickness of the printed slip c to be pastedupon the card. This leaves the surface of the slip of the same heightwith the surrounding edges of the intaglio space, and

when a great number of cards are thus provided with printed slips thetotal thickness at the point, where the slips are pasted will be nogreater than that of the outside edges.

The'cards will thus lie flat and smooth upon each other and will retaintheir shape and will not become worn or dogs-eared.

The intaglio space only appears upon one side, and the opposite side ofthe card is left perfectly smooth and flat so that it may be writtenupon in the usual way when written matter is to be used upon the card. 9

One method of accomplishing the desired.

'result is by cutting out a portion of a card equal in size to thedesired space and then folding the card and pasting it upon itself,one-half having the cut-away portion and being pasted upon the otherhalf which is left intact, Fig. 3. The thickness of the half which hasthe cut away portion will be equal to that of the slip which is to bepasted in the space.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is- 1 A card catalogue consisting of anindepend-v ent and'removable card adapted to stand on edge having oneofits sides smooth and flatand ruled, and its opposite side recessed atpoints inside of its marginal lines sufficient by to receive a slipwhich is pasted therein whereby the surface of the slip will not projectbeyond the plane of the face of the card, said card being formed of ablank folded centrally having a portion of one of its members out outand the two members foldedupon themselves,

and pasted together, whereby the depth of In witness whereof I havehereunto set my the depression formed by said out out-dpor hand. tion isequal to the thickness of the b0 y o theblank, and approximately equalto the ALEXANDER RUDOLPH 5 thickness of the slip, the whole card beingWitnesses:

formed as an integral whole, as herein de- S. H. NOURSE, scribed. J. A.BAYLESS.
